Topic: $50 robot design (Read 2849 times)

I wanted to get some opinions on my design before I start putting it together. Experience is always the best voice. Basiclly I am doing a revered trike. Battery is underslung green board on top will be my electronics. I a have not started that part yet. The rear caster has me a bit worried, mainly because it is cheap and may lock up. Will not really know until I try it though. And I had them so no cost there. I plan on putting the photoresitors in some sort of case and then mount them. Maybe a ball point pen case? Something along those lines. What sort of angle do they need to be at? I figure it is trial and error but a place to start would help. Anyway if you see anything blatantly wrong please let me know. I plan on starting construction next week. Oh do I need to use a breadboard to zero out the servos or can that be done once all the electronics are completed?

yeah everything is pretty close. I think the back wheel will need a spacer or two to keep the deck level with the front tires. Kinda hard to tell with sketch up. I wish it had a 3 pane view like some other modeling programs I have used. But I got out my ruler and measured everything. Deck is 4" wide and 8" long.

I may just have to do that. just to get a figure on how far the back wheel is off the ground. Sketch is not that bad to use. I still have trouble with the move tool, getting it to go the right way. which is why a 3 panel view would be cool. Maybe they will add it one day.
